Are you cooking with vegetable oils? According to lead scientists, this can be really unhealthy. When heated, these oils release toxic chemicals linked to cancer and other diseases. So do not use corn oil or sunflower oil for cooking. Or any refined oil. 

Olive oil (containing mainly monounsaturated fat) is a better option for cooking, but not great.The best option for cooking is saturated fats, like coconut oil, butter or lard. These fats can stand a lot of heat without transforming into poison.

Don’t use excessive heat when cooking. Make sure the food you cook can handle the heat.

And Stay Healthy.
